Coto Introduces Ground-Breaking BGA Relay
Coto Technology has introduced the first four independent channel, form-A, planar BGA Reed Relay. The B41 series is the latest offering in Coto's growing line of RF capable, reed relay products. Unlike Coto's B10, B40 and other high-performance RF reed relay products, no slot or hole in the PC board is required to mount the device - a feature which simplifies the design of multi-layer boards.
Coto's new, patented technology also allows for shorter RF paths in a controlled 50 ohm environment to minimize signal attenuation. Each channel has an RF insertion loss (-3dB roll-off point) of >8 GHz. A combination of coaxial and magnetic shielding reduces adjacent closed inter-channel RF crosstalk to -40dB at 1 GHz test signal and magnetic interaction between channels is reduced to < 16%
Applications include Mixed Signal & IC Testers where the B41's high package density and excellent RF performance are particularly important. BGA packaging, with JEDEC standard dimensions, allows B41 relays to be easily installed on PC boards designed for surface mount processing using either manual or automated pick-and-place techniques.
